In these examples we assume that the current log chatter value is 10 and
the commands are being processed in a command file that was invoked from
the terminal level using the @ convention, so that the nesting level is one.
XSPEC> log ! Turn on the log file (default x spec.log). Commands will not be logged from the indirect file, but will be logged on return to the terminal level.
XSPEC> log none ! Close the log file.
XSPEC> log mylog 9 ! Open the log file (mylog.log) and now even the indirect commands will be logged (at least for the first level of indirection).
XSPEC> log ,, 12 0 ! Now even at the terminal level the commands are not logged.
XSPEC> chatter ,, 12 ! Modifying the log file chattiness will restore command logging even at arbitrarily deep levels of indirection.
